[CentOS] kickstart and logins.def question

Hello all:

Happy New Year to everyone and thank you for all the knowledge this past year.

I have  a hopefully simple question about kickstart.   In the
authconfig section I can enable ldap, credential caching, etc.. Using
the GUI tool there's an option to create the user home directories on
first login. The docs don't show a similar option for authconfig in
kickstart.  For now I'm using a sed script in the %post section of the
kickstart to replace the entry in /etc/login.defs, but was curious if
there is a standard method via a system utility to change this option.
